Help with awk - read from file
Hi,

I've got a file like the following:

Code:
Starting to process segment 0 (and symmetry related segments)
	Number of (cancelled) singularities: 0
	Number of (cancelled) negative numerators: 0
	Segment 0: 5.49secs
Starting to process segment 1 (and symmetry related segments)
	Number of (cancelled) singularities: 0
	Number of (cancelled) negative numerators: 0
	Segment 1: 10.01secs
Starting to process segment 2 (and symmetry related segments)
	Number of (cancelled) singularities: 0
	Number of (cancelled) negative numerators: 0
	Segment 2: 7.82secs
Starting to process segment 3 (and symmetry related segments)
	Number of (cancelled) singularities: 0
	Number of (cancelled) negative numerators: 0
	Segment 3: 5.31secs

... and I would like to extract the information about the time. I would like to read the file, save the time (of each line) to a variable, remove the suffix secs and then add it to the previous value. The result will be the total time....

I tried many things but none of them works... In case it helps, the last one I tried was

Code:
 
TIME="`awk '/Segment/ {print $3%secs + $TIME} ' log.txt`"

echo $TIME

It's a silly solution, but I think it may convey what I want to do....
I suspect that it has something to do with reading each line separetely, but I can't figure it out...

Thanks a lot in advance...

qunbufcall

qunbufcall(9F)						   Kernel Functions for Drivers 					    qunbufcall(9F)

NAME

       qunbufcall - cancel a pending qbufcall request

SYNOPSIS

       #include <sys/stream.h>
	#include <sys/ddi.h>

       void qunbufcall(queue_t *q, bufcall_id_t id);

INTERFACE LEVEL

       Solaris DDI specific (Solaris DDI).

PARAMETERS

       q	Pointer to STREAMS queue_t structure.

       id	Identifier returned from qbufcall(9F)

DESCRIPTION

       qunbufcall()  cancels a pending qbufcall() request. The argument id is a non-zero identifier of the request to be cancelled. id is returned
       from the qbufcall() function used to issue the cancel request.

       The qunbufcall() function is tailored to be used with the enhanced STREAMS framework interface which is based on the concept of perimeters.
       (See   mt-streams(9F).)	qunbufcall() returns when the bufcall has been cancelled or finished executing. The bufcall will be cancelled even
       if it is blocked at the perimeters associated with the queue. All outstanding timeouts and bufcalls must be cancelled before a driver close
       routine can block and before the close  routine calls qprocsoff(9F).

CONTEXT

       qunbufcall() can be called from user or interrupt context.
